论文摘要
我们介绍了一组$ n $ photon连贯的状态，以及$ n $ photon的一组挤压连贯的状态，研究它们的崩溃和复兴，并将其行为与相应的零photon相干状态和零photon挤压的相应的相干状态进行比较。 $ n $ photon的集合挤压相干状态（$ n = 0,1,2，\ cdots $）构成了希尔伯特光子状态的基础，可能会引起某种兴趣。我们注意到，与相应的零 - 光子状态相比，在$ n $ photon状态中存在一些额外的光子，这在其崩溃和复兴的行为上具有很大的不同。这表明，与相应的零光子状态相比，$ n $ photon状态中的几个额外的光子在崩溃和复兴中产生的效果。
We introduce the set of $n$-photon coherent states and the set of $n$-photon squeezed coherent states and study their collapse and revival and compare their behavior with the collapse and revival of the corresponding zero-photon coherent states and zero-photon squeezed coherent states, respectively. The set of $n$-photon squeezed coherent states ($n=0,1,2,\cdots$) forms a basis of the Hilbert state of photons and may be of some interest. We notice that the presence of a few extra photons in the $n$-photon states as compared to the corresponding zero-photon states makes a large difference in the behavior of their collapse and revival. This indicates the large effect that a few extra photons makes in the $n$-photon states as compared to the corresponding zero-photon states in their collapse and revival.
